A solenoid type injector used in engines opens a valve and injects fuel
by moving a plunger with magnetic force created by an electromagnet.The
response for the applied voltage is evaluated to improve the fuel consumption
by maintaining the flow of fuel dispersed by an injector into an engine.Evaluating
ways to reduce the eddy currents to improve the response characteristics
of an injector is advantageous because the eddy currents produced by the
currents slow the response of the injector.
This example presents the use of a magnetic field analysis to obtain the
response characteristics of a solenoid type injector by evaluating ways
to reduce the amount of eddy currents.

| A solenoid valve opens and closes valves using the force of electromagnets.
A valve that controls the amount of fluid flowing has various states of
open and closed. For this reason, this analysis evaluates the response,
such as the speed and position control, of a valve to commands. Therefore,
an analysis that accounts for both the control and solenoid valve is necessary
to measure the response of the valve when it is moved.This example analyzes
the response of a solenoid valve using a control simulator and the JMAG-RT
system. |

| Solenoid injectors used for engines are mechanisms that spray fuel through
the valve which opens when the plunger is moved by magnetic force from
an electromagnet. Injectors in engines need to respond quickly to applied
voltage to improve fuel consumption by maintaining the fuel flow. In solenoid
injectors, one factor causing the response delay is eddy currents produced
by the current flow. This note presents the use of magnetic field analysis
to obtain the response characteristics of a solenoid injector. |

| A solenoid valve is a device that opens and closes the valve by moving
a plunger using electromagnetic force. Upon considering the effect of the
fluid stress caused by opening and closing the valve, it is important that
the attractive force is proportional to the drive current, and that a constant
attractive force is obtained regardless of the position of the iron core.
This note presents the use of magnetic field analysis to obtain the attractive
force of a solenoid valve at different positions of an iron core. |
